Danny Jacobs will be introduced as the WBA middleweight champion of the world on Saturday night when the Brooklyn product serves as a guest analyst for a boxing tripleheader on Showtime from Carson, Calif.

It’s a title Jacobs earned last Saturday night at Barclays Center, where he scored a dramatic fifth-round TKO over Jarrod Fletcher of Australia in their battle for a belt vacated when Gennady Golovkin was elevated to “Super Champion” status.

While the merit for multiple belts within the same sanctioning body and the same division can be debated, Jacobs winning a recognized world title is the latest feel-good story about an area boxer. First Chris Algieri of Long Island upset heavily favored Ruslan Provodnikov in June to capture the WBO light welterweight title. Now Jacobs, 27, has won a middleweight belt three years after undergoing surgery and treatment for a cancerous tumor wrapped around his spine.

“I’m glad I’m a world champion,” Jacobs told The Post. “But I still have a lot to prove. Winning a championship signifies I’ve accomplished a major goal. But there’s a lot more people I’d love to fight and lot more goals I’d like to take on.”

One of those is broadcasting. This will be the fifth opportunity for Jacobs to serve as a ringside analyst. The tripleheader features IBF welterweight champion Shawn Porter (24-0-1, 15 KOs) of Akron, Ohio, defending his title against Kell Brook (32-0, 22 KOs) of Sheffield, England; WBC super middleweight champion Sakio Bika (32-5-3, 21 KOs) of Australia defending against Anthony Dirrell (26-0-1, 22 KOs) of Flint, Mich.; and Omar Figueroa Jr. (23-0-1, 17 KOs) of Texas defending his WBC lightweight title against Daniel Estrada (32-2-1, 24 KOs) of Mexico.

“I think announcing fits me,” Jacobs said. “To be able to do something like this is very important to me.”

Jacobs was brilliant in his sixth fight since returning from 25 radiation treatments. He dropped Fletcher in the first round, but stayed patient, piling up the points and punches that finally made the Aussie succumb in the fifth.

“I’ve been soaking it all in,” Jacobs said. “But it’s been kind of hectic. I had to go into hibernation for a few days just to have some time to myself.”

Initially nicknamed the Golden Child after capturing four Golden Gloves titles as an amateur, Jacobs goes by the nickname Miracle Man to draw attention to his recovery and raise cancer awareness. On Wednesday, he will tour the Ronald McDonald House in Manhattan to meet with patients and their families. Meanwhile, he is plotting his first title defense after using his post-fight interview on Showtime to call out WBO middleweight champion Peter “Kid Chocolate” Quillin of Manhattan. The two are friends, and Quillin and Dirrell attended the launch party for Jacobs’ Get in the Ring Foundation in 2012.

“I feel like I had to do that because there’s no other way he’ll fight me,” Jacobs said. “We’re friends, but Peter knows this is a business.”

The matchup, pitting two local middleweight champions in a unification bout, would be the biggest boxing event yet to be held at Barclays Center.

“This one would take the cake,” Jacobs said. “I think a lot of people would be excited about this fight.”

Though both Jacobs (28-1, 25 KOs) and Quillin (31-0, 22 KOs) own belts, Golovkin is the recognized linear champion. That’s cool with Jacobs.

“He’s at the top of the throne. I’m working my way up even though I’m a champion,” the latest champion from Brownsville said. “People want to throw me in with the No. 1 guy, but I want to be a superstar when I fight Golovkin, so it can be worth all the marbles. That’s a multi-million dollar fight for both fighters. I want to get to that level before I fight that guy.”
